The applications of white, pink, and brown noise are diverse and far-reaching, encompassing various fields such as sound therapy, relaxation, and sleep enhancement. 

White noise is commonly used in environments where privacy and concentration are essential, such as offices, study spaces, and healthcare facilities.  Pink noise is often utilized in relaxation techniques, meditation practices, and even in the treatment of tinnitus and hyperacusis. Brown noise is favored for creating a sense of warmth and tranquility, making it ideal for sleep enhancement, stress reduction, and mindfulness exercises.

The use of these noises extends beyond individual well-being and therapeutic applications. They are also integrated into various forms of media, entertainment, and technology to enhance audio experiences, create immersive environments, and even aid in cognitive functions.

Brown noise vs white noise vs pink noise

White, pink, and brown noise are defined by their unique frequency distributions and sound characteristics, each of which has distinct effects on the human auditory system:

What is white noise?

White noise, often referred to as "true noise," contains all frequencies in equal amounts, creating a consistent and steady sound. It is commonly used to mask other sounds, aid in concentration, and promote better sleep.

What is pink noise?

Pink noise has a power spectral density that decreases by 3 dB per octave, making it sound more balanced to the human ear and is often used in sound therapy and relaxation techniques due to its soothing and calming effect. 

What is brown noise?

Brown noise, also known as Brownian noise, has more energy at lower frequencies (exhibits a power decrease of 6 dB per octave), creating a deeper and more rumbling sound, often used for relaxation, meditation, and creating a sense of warmth and comfort.
